[0028] In the existing foam generating device, generating foam requires continuous injection of foam liquid, and the foam liquid cannot be fully mixed with water for foaming, and it is impossible to ensure accurate liquid consumption when the liquid consumption of the foam liquid is small during single foaming.
[0029] Based on the above problems, the present application proposes a foam generating device and a toilet. By arranging a foam liquid accommodating member in the first accommodating space of the housing, the foam liquid accommodating member has a second accommodating space, and the foam liquid accommodating member is provided with a foam liquid inlet, a second water inlet and a second mixed liquid outlet, which can effectively solve the above problems.
[0030] The following describes in detail a foam generating device and a toilet provided by the present application with reference to the drawings and embodiments.
[0031] The present application provides a foam generating device. Please refer to Figure 1 And Figures 2 to 6 , Figure 1 is a schematic structural diagram of an embodiment of the foam generating device of the present application; Figure 2 is Figure 1 a schematic vertical cross-sectional structure diagram of an embodiment of the liquid mixing assembly in the foam generating device; Figure 3 is Figure 1 a schematic horizontal cross-sectional structure diagram of an embodiment of the liquid mixing assembly in the foam generating device; Figure 4 is Figure 1 a schematic structural diagram of a first embodiment of the foam liquid accommodating member in the foam generating device; Figure 5 is Figure 1 a schematic structural diagram of a second embodiment of the foam liquid accommodating member in the foam generating device; Figure 6 is Figure 1 a schematic structural diagram of a first perspective of the liquid mixing assembly in the foam generating device; Figure 7 is Figure 1 a schematic structural diagram of a second perspective of the liquid mixing assembly in the foam generating device. In some embodiments, the foam generating device 100 includes a liquid mixing assembly 10, and the liquid mixing assembly 10 includes a housing 110 and a foam liquid accommodating member 120.
[0032] Among them, the foam generating device 100 provided in this application can specifically be used to be arranged in a toilet. The foam generating device 100 can be used to provide foam for the cleaning water in the cleaning water path of the toilet. The foam generating device 100 can also be used to provide foam for the flushing water path of the toilet. Of course, in some other embodiments, the foam generating device 100 can also be used to be arranged in any reasonable water outlet device such as a shower head, and this embodiment does not limit this.
[0033] The liquid mixing assembly 10 includes a housing 110 and a foam liquid accommodating member 120. The housing 110 has a first accommodating space 111, and the housing 110 is provided with a first water inlet 112 and a first mixed liquid outlet 113. The foam liquid accommodating member 120 is arranged in the first accommodating space 111, and the foam liquid accommodating member 120 has a second accommodating space 121. The foam liquid accommodating member 120 is provided with a foam liquid input port 125, one or more second water inlets 123, and one or more second mixed liquid outlets 124. Among them, the distance between the second water inlet 123 and the first water inlet 112 is less than the distance between the second mixed liquid outlet 124 and the first water inlet 112.
[0034] The liquid mixing assembly 10 is used to mix the foam liquid and water to dilute the foam liquid. Among them, the housing 110 and the first accommodating space 111 inside the housing 110 can specifically be in the shape of a rectangular body, a cylinder, a frustum, an irregular polygon, etc. The first water inlet 112 is used to connect to a water pump to inject water for mixing and diluting the foam liquid into the first accommodating space 111 through the first water inlet 112. The first mixed liquid outlet 113 is used to output the mixed liquid mixed and diluted by the liquid mixing assembly 10 to the foaming nozzle 30 to generate foam from the mixed liquid. Different from the existing liquid mixing assembly 10, the liquid mixing assembly 10 in this embodiment has a foam liquid accommodating member 120 in the first accommodating space 111. The foam liquid accommodating member 120 can be used to temporarily store the injected foam liquid. Among them, the foam liquid accommodating member 120 and its internal second accommodating space 121 can specifically be in the shape of a rectangular body, a cylinder, a frustum, an irregular polygon, etc.
[0035] In this embodiment, both the first accommodating space 111 and the foam liquid accommodating member 120 are in the shape of a cylinder, and the side wall of the foam liquid accommodating member 120 is surrounded by the first accommodating space 111. And the second water inlet 123 and the second mixed liquid outlet 124 are arranged on the side wall of the foam liquid accommodating member 120. This setting ensures that a liquid flow path surrounding the foam liquid accommodating member 120 is formed in the first accommodating space 111, and the liquid can pass through the second water inlet 123 on the foam liquid accommodating member 120 when flowing along the liquid flow path.
[0036] In a specific application scenario where the liquid mixing assembly 10 mixes and dilutes the mixed liquid with water, the pump first sucks in a part of the foam liquid and inputs it into the first accommodation space 111 through the foam liquid inlet 125. The pump sucks in water from the first water inlet 112 and enters the first accommodation space 111. During the flowing process of the water entering the first accommodation space 111, it first passes through the second water inlet 123 near the first water inlet 112, and part of the water enters the second accommodation space 121 from the second water inlet 123. The water entering the second accommodation space 121 undergoes the first mixing and dilution with the foam liquid. The water that does not enter the second accommodation space 121 continues to flow, and when it flows to the second mixed liquid outlet 124, according to Bernoulli's principle: the greater the flow rate, the smaller the pressure, so that the pressure outside the second mixed liquid outlet 124 in the second accommodation space 121 is less than the pressure inside the second accommodation space 121. The change in pressure causes the initially mixed liquid in the second accommodation space 121 to flow out from the second mixed liquid outlet 124 and collide and mix with the water in the first accommodation space 111 for the second time. As described above, the liquid mixing assembly 10 can mix the foam liquid and water multiple times to ensure the full mixing and dilution of the foam liquid.
[0037] Different from the prior art, the present application provides a foam generating device 100. The foam generating device 100 has a liquid mixing assembly 10. The foam liquid can be temporarily stored in the second accommodation space 121, and it is not necessary to inject the foam liquid every time foam is generated. In the mixing process of the foam liquid, the water in the first accommodation space 111 enters the second accommodation space 121 through the second water inlet 123 and undergoes the first mixing and dilution with the foam liquid. After the water and the foam liquid are mixed, they flow to the first accommodation space 111 from the second mixed liquid outlet 124 due to the pressure effect and undergo the second mixing with the water in the first accommodation space 111. The above two mixing processes can ensure the full mixing of the water and the foam liquid. And with the above arrangement, for the consumption of the foam liquid, the water first enters the first accommodation space 111 to dilute the foam liquid. Every time foam is generated, part of the diluted foam liquid flowing out from the second mixed liquid outlet 124 is mixed again and used to generate foam. The single consumption of the foam liquid can be controlled to be lower, so as to ensure the accurate consumption of the foam liquid.
[0038] In some embodiments, the foam generating device 100 further includes a foam liquid storage tank 20. The liquid mixing assembly 10 further includes a peristaltic pump 130. The peristaltic pump 130 is disposed on the housing 110. The peristaltic pump 130 is connected to the foam liquid storage tank 20 and is also connected to the foam liquid inlet 125 of the foam liquid accommodating member 120. Specifically, the peristaltic pump 130 can generate a high vacuum degree, has the characteristics of high precision, and can perform precise flow control. By using the peristaltic pump 130 to replace the diaphragm liquid pump for sucking the foam liquid, the accurate consumption of the foam liquid can be further ensured. On the other hand, the valve-free design structure of the peristaltic pump 130 and the fact that the peristaltic pump 130 transports fluids by squeezing the pump tube make the peristaltic pump 130 have no fixed small holes or narrow points, avoiding the risk of blockage caused by the solidification of the foam liquid when the peristaltic pump 130 is not used for a long time. Among them, the foam liquid storage tank 20 can be detachably fixed to the housing 110 by any reasonable structure such as a screw structure, a bolt structure, a clamping structure, etc.
[0039] Among them, the housing 110 plays a role of support and protection. For the convenience of transportation and the protection of internal components, the housing 110 can be made by injection molding with plastics having a relatively light weight and good stamping resistance. For example, the manufacturing materials of the housing 110 can include one or more of ABS (ternary copolymer of acrylonitrile, butadiene, and styrene), PC (polycarbonate), PET (polyethylene terephthalate), etc.
[0040] In some embodiments, the foam liquid accommodating member 120 is in a cylindrical shape. The foam liquid inlet 125 is disposed on the bottom wall of the foam liquid accommodating member 120. The second water inlet 123 and the second liquid mixing outlet 124 are disposed on the side wall of the foam liquid accommodating member 120. The peristaltic pump 130 is connected to the foam liquid inlet 125 through the housing 110. Among them, a liquid flow channel surrounding the side wall of the foam liquid accommodating member 120 is formed in the first accommodating space 111. The first water inlet 112 is located at one end of the liquid flow channel, and the first liquid mixing outlet 113 is located at the other end of the liquid flow channel. Specifically, in this embodiment, a liquid flow channel is formed in the first accommodating space 111. One end of the liquid flow channel is the first water inlet 112, and the other end of the liquid flow channel is the first liquid mixing outlet 113. And along the direction towards the first liquid mixing outlet, the second water inlet 123 and the second liquid mixing outlet 124 are arranged in sequence, so that the water entering the first accommodating space 111 from the first water inlet 112 can first pass through the second water inlet 123, and part of the water enters the second accommodating space 121 for the first mixing and dilution, and the other water continues to flow to the second liquid mixing outlet 124, driving the change of pressure, so that the liquid in the second accommodating space 121 flows out from the second liquid mixing outlet 124 for the second mixing and dilution, ensuring the full mixing of the liquid mixture.
[0041] Further, in this embodiment, a second water inlet 123 and a second mixed liquid outlet 124 are provided on the foam liquid container 120. In some other embodiments, two, three or other reasonable numbers of second water inlets 123 can also be provided on the foam liquid container 120. Similarly, the number of second mixed liquid outlets 124 can also be two, three, four or other reasonable numbers. Among them, the shape of the second water inlet 123 can be any one of a circle, a square, and an irregular polygon; the shape of the second mixed liquid outlet 124 can be any one of a circle, a square, and an irregular polygon. The shapes of the second water inlet 123 and the second mixed liquid outlet 124 can also be any other reasonable shapes, and this embodiment does not make specific limitations on this.
[0042] Further, in a specific application scenario, the size and number of the second water inlet 123 can be determined according to the ratio of the foam liquid to be mixed with water during use, and the rate of water entering the second accommodation space 121 from the first accommodation space 111 can be adjusted by setting different second water inlets 123, so as to achieve the best dilution degree when the foam liquid is used. For example, when the viscosity of the foam liquid is high and the foam liquid needs to be mixed with more water, the structure of the foam liquid container 120 can be as Figure 5 shown, Figure 5 In the embodiment, by setting the second water inlet 123 on the foam liquid container 120 to be larger in size, the rate of water entering the second accommodation space 121 is faster, so that more water in the first accommodation space 111 can enter the second accommodation space 121 to be mixed with the foam liquid; or in some other embodiments, more second water inlet holes 123 can also be opened on the foam liquid container 120 to achieve the best dilution degree for the foam liquid with a higher viscosity. When the viscosity of the foam liquid is low and the foam liquid needs to be mixed with less water, the structure of the foam liquid container 120 can be as Figure 4 shown, Figure 4 In the embodiment, by setting the second water inlet 123 on the foam liquid container 120 to be smaller in size, the best dilution degree of the foam liquid can be achieved; or in some other embodiments, the best dilution degree of the foam liquid with a lower viscosity can also be achieved by opening fewer second water inlet holes 123.
[0043] In this embodiment, the liquid mixing assembly 10 further includes a first baffle 114 and a second baffle 115. The first baffle 114 is disposed in the first accommodation space 111, and the first baffle 114 is correspondingly disposed opposite the first water inlet 112. The first baffle 114 is located between the first water inlet 112 and the first mixed liquid outlet 113, and the first baffle 114 has a blocking surface facing the first water inlet 112 and the second water inlet 123. The second baffle 115 is disposed in the first accommodation space 111, and the second baffle 115 has a blocking surface facing the first mixed liquid outlet 113. Specifically, the first baffle 114 is provided to prevent the water entering from the first water inlet 112 from directly flowing out from the first mixed liquid outlet 113, so that at least part of the water entering from the first water inlet 112 can be blocked by the first baffle 114 and then flow towards the second water inlet 123 on the foam liquid accommodating member 120, so that the water can enter the second accommodation space 121 to be first mixed and diluted with the foam liquid. The second baffle 115 is provided so that after the foam liquid is diluted twice in the second accommodation space 121 and the first accommodation space 111, it can be blocked by the second baffle 115 during the flowing process and then flow out from the first mixed liquid outlet 113. Among them, the first baffle 114 and the second baffle 115 can be square, circular, irregular polygon, etc., without specific limitation.
[0044] In this embodiment, a balance hole 122 is formed at the top of the foam liquid accommodating member 120. Specifically, the balance hole 122 is provided to maintain the relative pressure balance between the first accommodation space 111 and the second accommodation space 121, so as to ensure that the water in the first accommodation space 111 can smoothly enter the second accommodation space 121 from the second water inlet 123. Among them, the number of the balance holes 122 can be one or more, and the shape of the balance holes 122 is not specifically limited either.
[0045] Further, in this embodiment, the foam liquid accommodating member 120 is clamped and fixed in the first accommodation space 111. In some other embodiments, the foam liquid accommodating member 120 and the housing 110 can also be integrally formed structures, without specific limitation.
[0046] In this embodiment, the foam generating device 100 further includes: a foaming nozzle 30, and the foaming nozzle 30 is connected to the first mixed liquid outlet 113 of the housing 110. Specifically, the foaming nozzle 30 is used to foam the foam liquid that has been fully mixed and diluted by the liquid mixing assembly 10. Preferably, in this embodiment, the foaming nozzle 30 is a Venturi tube nozzle. In some other embodiments, the foaming nozzle 30 can also be other types of foaming nozzles 30 such as a porous nozzle and a vortex nozzle, and the type of the foaming nozzle 30 is not specifically limited.
[0047] In this embodiment, the housing 110 has a third accommodation space (not labeled), and the peristaltic pump 130 is disposed in the third accommodation space. The housing 110 is formed with a foam liquid transmission channel 131 that communicates the first accommodation space 111 with the third accommodation space. Specifically, a check valve 140 is provided on the foam liquid transmission channel 131. Specifically, the check valve 140 is configured to prevent the liquid in the first accommodation space 111 and the second accommodation space 121 from entering the third accommodation space. In some other embodiments, a seal may also be provided on the foam liquid transmission channel 131 to avoid the risk of leakage of the foam liquid transmission channel 131.
[0048] Different from the prior art, the present application provides a foam generating device 100. The foam generating device 100 has a liquid mixing assembly 10. The foam liquid can be temporarily stored in the second accommodation space 121, and it is not necessary to inject the foam liquid every time foam is generated. During the mixing process of the foam liquid, the water in the first accommodation space 111 enters the second accommodation space 121 through the second water inlet 123, and is first mixed and diluted with the foam liquid. After the water and the foam liquid are mixed, they flow into the first accommodation space 111 from the second mixed liquid outlet 124 due to the pressure effect, and are secondarily mixed with the water in the first accommodation space 111. The above two mixing processes can ensure the sufficient mixing of the water and the foam liquid. With the above arrangement, for the consumption of the foam liquid, the water first enters the first accommodation space 111 to dilute the foam liquid. Each time foam is generated, a part of the diluted foam liquid flows out from the second mixed liquid outlet 124 and is mixed again for generating foam. The single consumption of the foam liquid can be controlled to be lower, thereby ensuring the accurate consumption of the foam liquid.
[0049] Correspondingly, the present application also proposes a toilet, which includes a toilet bowl and a foam generating device. The foam generating device is disposed corresponding to the toilet bowl, and the foam generating device is the foam generating device described in any of the above embodiments.
